I am a passionate individual who enjoys creating new insights for people. I have contributed to the Elasticsearch Java open-source project and am currently seeking more opportunities to contribute. With my proficiency in zero-downtime CI/CD deployment, I am also studying ways to create efficient testing pipelines using these deployment methods.
